M by Missoni knit tank

M by Missoni rib knit tank in peach with turquoise stripes and hem. No care or size tag. Worn once. Near perfect condition with a couple of tiny pulls that are barely noticable. I don't know the textile content, but it feels like a high-end, nylon blend, not scratchy at all and very stretchy. Fits like a S/XS. I am a 0/2, and while it fits me, there's definitely room for a larger person, probably a 4.
